Sudden gains in cognitive therapy of depression and depression relapse/recurrence

Cognitive therapy (CT) may have significant advantages over antidepressants in preventing depression relapses. Many CT patients experience sudden gains: large symptom improvement in 1 between-session interval. Past studies have associated CT sudden gains with in-session cognitive changes but not with life events. This study examined sudden gains and depression relapse/recurrence among 60 CT clinical-trial patients. Survival analyses showed that only one third of sudden-gain-responders relapsed in 2 years, and they had 74% lower relapse risks than did non-sudden-gain-responders. Among patients with sustained responses, 73% experienced sudden gains. The authors also replicated J. R. Vittengl, L. A. Clark, and R. B. Jarrett's finding that sudden gains identified with their unique criteria did not predict relapse. The current authors' findings suggest that CT sudden gains are not measurement artifacts, and that sudden gains and their causes and consequences might be important in preventing relapses.     

Prevention of relapse/recurrence in major depression by mindfulness-based cognitive therapy

This study evaluated mindfulness-based cognitive therapy (MBCT), a group intervention designed to train recovered recurrently depressed patients to disengage from dysphoria-activated depressogenic thinking that may mediate relapse/recurrence. Recovered recurrently depressed patients (n = 145) were randomized to continue with treatment as usual or, in addition, to receive MBCT. Relapse/recurrence to major depression was assessed over a 60-week study period. For patients with 3 or more previous episodes of depression (77% of the sample), MBCT significantly reduced risk of relapse/recurrence. For patients with only 2 previous episodes, MBCT did not reduce relapse/recurrence. MBCT offers a promising cost-efficient psychological approach to preventing relapse/recurrence in recovered recurrently depressed patients.     

Duration of relapse prevention after cognitive therapy in residual depression: follow-up of controlled trial

BACKGROUND: Although there is good evidence that cognitive therapy (CBT) lessens relapse and recurrence in unipolar depression, the duration of this effect is not known. METHOD: One hundred and fifty-eight subjects, from a randomized controlled trial of CBT plus medication and clinical management versus medication and clinical management alone, were followed 6 years after randomization (4 1/2 years after completion of CBT) and the longitudinal course assessed. RESULTS: Effects in prevention of relapse and recurrence were found to persist, with weakening, and were not fully lost until 3 1/2 years after the end of CBT. Residual symptoms were also lessened. CONCLUSIONS: The effect of CBT in reduction of relapse and recurrence persists for several years. The potential value of subsequent additional CBT some time after cessation should be explored.     

Deterioration in psychosocial functioning predicts relapse/recurrence after cognitive therapy for depression

BackgroundAssociations between major depressive disorder (MDD) and psychosocial functioning are incompletely understood across time and during continuation phase cognitive therapy (C-CT). We examined the validity of the Range of Impaired Functioning Tool (RIFT; [Leon, A.C., Solomon, D.A., Mueller, T.I., Turvey, C.L., Endicott, J., Keller, M.B., 1999. The Range of Impaired Functioning Tool (LIFE-RIFT): A brief measure of functional impairment. Psychol. Med. 29, 869–878.]) as a measure of psychosocial functioning and its relations to depressive symptoms in C-CT and assessment-only control conditions.MethodsOutpatients with recurrent MDD who responded to acute-phase cognitive therapy (A-CT) were randomized to 8 months of C-CT (n = 41) or assessment-only (n = 43) and followed 16 additional months [Jarrett, R.B., Kraft, D., Doyle, J., Foster, B.M., Eaves, G.G., Silver, P.C., 2001. Preventing recurrent depression using cognitive therapy with and without a continuation phase: A randomized clinical trial. Arch. Gen. Psychiatry 58, 381–388.]. Interviewers rated depressive symptoms and psychosocial functioning monthly. Patients completed additional self-reports.ResultsThe RIFT converged appropriately with other measures of psychosocial functioning, depressive symptoms, cognitive content, and personality. About half (55%) of patients were psychosocially “well” (RIFT ≤ 8) during the first month post-A-CT. C-CT improved psychosocial functioning only transiently compared to the assessment control. Examined prospectively, depressive symptom level did not predict monthly changes in psychosocial functioning significantly, whereas psychosocial dysfunction level predicted monthly changes in depressive symptoms and relapse/recurrence.LimitationsFindings may not generalize to other patient populations, treatments, and assessment methods. The cross-lagged correlational data structure allows only tentative conclusions about the causal effect of psychosocial functioning on depressive symptoms.ConclusionsThe RIFT is a valid measure of psychosocial functioning among responders to A-CT for depression. After such response, deteriorations in psychosocial functioning may signal imminent major depressive relapse/recurrence and provide targets for change during treatments focused on relapse/recurrence prevention.

Early intervention for relapse in schizophrenia: results of a 12-month randomized controlled trial of cognitive behavioural therapy

BACKGROUND: The paper describes a randomized controlled trial of targeting cognitive behavioural therapy (CBT) during prodromal or early signs of relapse in schizophrenia. We hypothesized that CBT would result in reduced admission and relapse, reduced positive and negative symptoms, and improved social functioning. METHOD: A total of 144 participants with schizophrenia or a related disorder were randomized to receive either treatment as usual (TAU) (N = 72) or CBT+TAU (N = 72). Participants were prospectively followed up between entry and 12 months. RESULTS: At 12 months, 11 (15.3%) participants in the CBT group were admitted to hospital compared to 19 (26.4%) of the TAU group (hazard ratio = 0.53, P = 0.10, 95% CI 0.25, 1.10). A total of 13 (18.1%) participants in CBT relapsed compared to 25 (34.7%) in TAU (hazard ratio = 0.47, P < 0O05, 95% CI 0.24, 0.92). In addition, the CBT group showed significantly greater improvement in positive symptoms, negative symptoms, global psychopathology, performance of independent functions and prosocial activities. CONCLUSIONS: The study provides evidence for the feasibility and effectiveness for targeting CBT on the appearance of early signs of relapse in schizophrenia. The results are discussed in context of the study's methodological limitations.     

Online randomized controlled trial of brief and full cognitive behaviour therapy for depression

BACKGROUND: Effective internet-based programs for depression usually incorporate a component that provides telephone or email contact. Open access websites, without such contact, show high rates of attrition and poorer outcomes. The present study was designed as an exploratory investigation of the parameters that influence the effectiveness and retention of users on open access websites. We investigated whether brief cognitive behaviour therapy (CBT) was as effective as an extended version, whether add-on components of behaviour therapy or stress management contributed to positive outcomes, and whether longer programs were associated with greater attrition. METHOD: An online randomized controlled trial (RCT) was conducted between 13 January 2005 and 26 May 2005 (19 weeks). A total of 2794 registrants (1846 women and 948 men; median age category 35-44 years) with elevated scores on the Goldberg Depression Scale of 5.96 (S.D.=2.09) elected online to be randomized to one of six versions of a CBT website. The versions were compiled consisting of various components of brief CBT, extended CBT, behaviour strategies, stress management and problem solving. RESULTS: A total of 20.4% of participants completed the assigned intervention. The interaction of measurement occasion and treatment version was significant [F(13,131)=2.20, p=0.01]. A single module of brief introductory CBT was not effective in reducing depression symptoms. However, extended CBT with or without the addition of behaviour strategies resulted in the reduction of depression. CONCLUSIONS: Brief CBT-based interventions are not as effective as extended interventions. However, longer programs are associated with higher rates of dropout.     

Brief cognitive therapy for panic disorder: a randomized controlled trial.

Cognitive therapy (CT) is a specific and highly effective treatment for panic disorder (PD). Treatment normally involves 12-15 1-hr sessions. In an attempt to produce a more cost-effective version, a briefer treatment that made extensive use of between-sessions patient self-study modules was created. Forty-three PD patients were randomly allocated to full CT (FCT), brief CT (BCT), or a 3-month wait list. FCT and BCT were superior to wait list on all measures, and the gains obtained in treatment were maintained at 12-month follow-up. There were no significant differences between FCT and BCT. Both treatments had large (approximately 3.0) and essentially identical effect sizes. BCT required 6.5 hr of therapist time, including booster sessions. Patients' initial expectation of therapy success was negatively correlated with posttreatment panic-anxiety. Cognitive measures at the end of treatment predicted panic-anxiety at 12-month follow-up.     

Internet-based cognitive behavioural therapy for subthreshold depression in people over 50 years old: a randomized controlled clinical trial

BACKGROUND: Subthreshold depression is a highly prevalent condition and a risk factor for developing a major depressive episode. Internet-based cognitive behaviour therapy may be a promising approach for the treatment of subthreshold depression. The current study had two aims: (1) to determine whether an internet-based cognitive behaviour therapy intervention and a group cognitive behaviour therapy intervention are more effective than a waiting-list control group; and (2) to determine whether the effect of the internet-based cognitive behaviour therapy differs from the group cognitive behaviour therapy intervention. METHOD: A total of 191 women and 110 men with subthreshold depression were randomized into internet-based treatment, group cognitive behaviour therapy (Lewinsohn's Coping With Depression course), or a waiting-list control condition. The main outcome measure was treatment response after 10 weeks, defined as the difference in pre- and post-treatment scores on the Beck Depression Inventory (BDI). Missing data, a major limitation of this study, were imputed using the Multiple Imputation (MI) procedure Data Augmentation. RESULTS: In the waiting-list control group, we found a pre- to post-improvement effect size of 0.45, which was 0.65 in the group cognitive behaviour therapy condition and 1.00 within the internet-based treatment condition. Helmert contrasts showed a significant difference between the waiting-list condition and the two treatment conditions (p=0.04) and no significant difference between both treatment conditions (p=0.62). CONCLUSIONS: An internet-based intervention may be at least as effective as a commonly used group cognitive behaviour therapy intervention for subthreshold depression in people over 50 years of age.     

Web-based cognitive behavior therapy for depression with and without telephone tracking in a national helpline: secondary outcomes from a randomized controlled trial

Background

An earlier report indicated that callers to a telephone counseling service benefited from the addition of an evidence-based Web intervention for depression. It is not known whether the Web intervention would also lower alcohol use and stigma, or improve quality of life and knowledge of depression and its treatments.

Objective

To report the secondary outcomes of a trial of a Web-based cognitive behavior therapy (CBT) intervention for depression, including hazardous alcohol use, quality of life, stigma, depression literacy, and CBT literacy.

Methods

We recruited a sample of 155 callers to Lifeline, a national telephone counseling service in Australia, who met the criteria for moderate to high psychological distress. Participants were randomly assigned to 1 of 4 conditions: (1) Web CBT plus weekly telephone tracking, (2) Web CBT only, (3) weekly telephone tracking only, and (4) neither Web CBT nor telephone tracking. Participants were assessed at preintervention, postintervention, and 6 and 12 months postintervention.

Results

At postintervention, participants who completed the Web intervention either with or without telephone support had lower levels of hazardous alcohol use (without tracking: P = .008, effect size = 0.23; with tracking: P = .003, effect size = 0.26), improved quality of life (without tracking: P = .001, effect size = 0.81; with tracking: P = .009, effect size = 0.63), and improved CBT literacy (without tracking: P = .01, effect size = 0.71; with tracking: P < .001, effect size = 0.80) compared with those who did not receive the Web intervention or telephone support. Results for quality of life and CBT literacy were maintained at 6- and 12-month’s follow-up, but differences in hazardous alcohol use were not significantly different between conditions at 6 and 12 months. Although omnibus tests for depression literacy and stigma were nonsignificant, contrasts revealed that those in the Web-only condition showed significantly lower levels of stigma than participants in the control condition at postintervention. This was true for participants in the Web-only and Web plus tracking conditions at 6 months. Similarly, those in the Web-only and Web plus tracking conditions had significantly higher depression literacy at postintervention, and this was maintained in the Web-only condition at 6-months’ follow-up. No significant differences were found in depression literacy and stigma between conditions at 12 months.

Conclusions

Evidence-based Web interventions for depression can be effective not only in reducing depression symptoms but also in improving other health outcomes, including quality of life, hazardous alcohol use, and knowledge about effective strategies for depression self-management.

Effects of cognitive behavioural therapy on verbal learning and memory in major depression: Results of a randomized controlled trial

Major depression (MD) is often accompanied by deficits in cognitive functioning. Cognitive behavioural therapy (CBT) has beneficial effects on MD. The aim of this study was to examine whether CBT affects verbal learning and memory in patients with MD and whether CBT that emphasizes exercise during behavioural activation has additional effects on verbal performance. Ninety‐eight patients with MD were randomly assigned to CBT emphasizing either exercise during behavioural activation (CBT‐E) or CBT emphasizing pleasurable low‐energy activities (CBT‐C). A passive waiting list control group was also involved (WL). Thirty nondepressed age‐ and sex‐matched controls were included to examine potential verbal learning and memory alterations in MD at baseline. Neuropsychological measures were assessed at baseline and after 16 weeks of CBT and waiting time, respectively. Patients with MD demonstrated worse cognitive performance than healthy controls in verbal learning, recognition, and memory at baseline. After treatment, we found no improvements concerning verbal learning and memory performance compared with WL, with the exception of recognition memory. No differences were found between CBT conditions. Psychological treatments such as CBT seem to have limited influence on memory functions. Concerning recognition memory, our results contradict, in part, previous assumptions that cognitive impairments persists despite depressive symptom reduction.     

Psychotherapy for depression: A randomized clinical trial comparing schema therapy and cognitive behavior therapy

Background

The efficacy of Cognitive Behavior Therapy (CBT) for depression has been robustly supported, however, up to fifty percent of individuals do not respond fully. A growing body of research indicates Schema Therapy (ST) is an effective treatment for difficult and entrenched problems, and as such, may be an effective therapy for depression.

Methods

In this randomized clinical trial the comparative efficacy of CBT and ST for depression was examined. 100 participants with major depression received weekly cognitive behavioral therapy or schema therapy sessions for 6 months, followed by monthly therapy sessions for 6 months. Key outcomes were comparisons over the weekly and monthly sessions of therapy along with remission and recovery rates. Additional analyses examined outcome for those with chronic depression and comorbid personality disorders.

Results

ST was not significantly better (nor worse) than CBT for the treatment of depression. The therapies were of comparable efficacy on all key outcomes. There were no differential treatment effects for those with chronic depression or comorbid personality disorders. Limitations: This study needs replication.

Conclusions

This preliminary research indicates that ST may provide an effective alternative therapy for depression.     

A randomized controlled trial of mindfulness-based cognitive therapy for treating tinnitus

We conducted a randomized clinical trial to examine the relative effectiveness of two psychological interventions for treating tinnitus. People with tinnitus were initially offered a single session of psychoeducation about tinnitus, followed 2 months later by six weekly sessions of either mindfulness or relaxation training. Results indicated benefits from psychoeducation in reducing negative emotions, rumination and psychological difficulties of living with tinnitus. These effects were maintained or enhanced by mindfulness training that also emphasized acceptance, although they were eroded in the relaxation condition over the follow-up. Mediating processes are discussed, and suggestions for refining clinical interventions for this population are offered. KEY PRACTITIONER MESSAGE: The present results suggest that mindfulness training might constitute a useful addition to psychoeducation for interventions targeting the psychological consequences of tinnitus.     

Randomized trial of behavioral activation, cognitive therapy, and antidepressant medication in the prevention of relapse and recurrence in major depression

This study followed treatment responders from a randomized controlled trial of adults with major depression. Patients treated with medication but withdrawn onto pill-placebo had more relapse through 1 year of follow-up compared to patients who received prior behavioral activation, prior cognitive therapy, or continued medication. Prior psychotherapy was also superior to medication withdrawal in the prevention of recurrence across the 2nd year of follow-up. Specific comparisons indicated that patients previously exposed to cognitive therapy were significantly less likely to relapse following treatment termination than patients withdrawn from medication, and patients previously exposed to behavioral activation did almost as well relative to patients withdrawn from medication, although the difference was not significantly different. Differences between behavioral activation and cognitive therapy were small in magnitude and not significantly different across the full 2-year follow-up, and each therapy was at least as efficacious as the continuation of medication. These findings suggest that behavioral activation may be nearly as enduring as cognitive therapy and that both psychotherapies are less expensive and longer lasting alternatives to medication in the treatment of depression.
